nvme-hwmon: rework to avoid devm allocation
[ Upstream commit ed7770f6 ] The original design to use device-managed resource allocation doesn't really work as the NVMe controller has a vastly different lifetime than the hwmon sysfs attributes, causing warning about duplicate sysfs entries upon reconnection. This patch reworks the hwmon allocation to avoid device-managed resource allocation, and uses the NVMe controller as parent for the sysfs attributes.
